I meant a successful one in the same scale as PUBG. I even mentioned King of the Kill in my post.
To be fair, H1Z1 King of the Kill was successful at one point that they were hitting over 100k viewers on Twitch with big streamers like Summit, Doc, Ninja and more that streamed it before PUBG became a thing.
I feel like they weren't fast enough to capitalise on the success and took too long which is why PUBG is now #1. I believe I read an article that the Zombie aspect of the game was meant to come out in 2016 on Xbox One and PS4 and it never did. It's a shame since the game plays similarly to Fortnite minus the building and would've been really good.
